MEANS FOR REGULATING THE FLOW 0F ARTESIAN AND GAS WELLS.

SSPEC'Il-CATON forming part of Letters Patent 1\l'o.310,0661` dated December 30, 1884-,

Be it known that we, Janus J. )idrici-in, of Freeport, and Josnrir (fr. BELLE, of Leechburg, in the county of Armstrong and State of llennsylvania, have invented certain new and useful Improvements in Means for Regulating the Elow vfrom Artesian and Gas Vells; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a par-t of' this Specification.

Our invention has relation to means for regulating the flow of' gas or i'luids from Artcsian wells, and has for its object to provide apparatus by which the fiow may be limited to any desired pressure or entirely cut off.

Our invention consists in the provision of a plug of rubber adapted to be placed in the well below the casing,provided with a central orifice :lor the passage of the gas or fluid, said orifice being governed by a valve or cock, and

the plug being so constructed that it will be held in position in the well by the pressure of the gas or fluid from beneath.

Qur invention further consists in the pro? vision of aplug of lrubber adapted to be placed in the well below the casing. and having a iiange upon its botto1n, which will be pressed out against the side ofthe well by the pressure ofthe gas or fluid from beneath, and provided with a central orifice, to which is fitted a section of' pipe provided with a cock or valve t'or regulating the flow of gas or fluid.

Our invention still further consists iu a plug t'or 'wellscoinprising a body of rubber having a central opening for the reception ot' a pipe, to which is` applied a governing` valve or cock, saidpipe having a flangebelow the bottom of the said plug, whereby it :is retained in position ltherein.

Our invention still further consists in the novel construction, combination, and arrangement of parts, as hereinafter fully described and specifically claimed.

Referring to the accompanying drawings, Figurel represents a section of' a well with our improvement in position therein. Fig. 2 is a similar view of a modification.

In 1F10'. 1 the plug is provided with a section of pipe long enough to reach to the surface of' the earth, while in FiO. 2 the section of pipe which is fitted to the plug is short, and the valve or cock is placed immediately above the plug` and operated by means of leadingwvires from above.

A designates the well; B'Lthe usual easing inserted in the well and reaching from the surface to a point below the water-line. This casing is of the ordinary construction, and may E, which is provided with a suitable valve orV cock, F, which, when the section of pipe is short, is operated by leading-wiresff, as shown in Fig. 2; but when the pipe is long enough to reach tothe su rf'aee of the earth,as shownin Fig. l, is operated directly byhand. rlhe upper edge of the plug Gis beveled oft', as shown at g, so as to receive a ring, G, which serves to assist in retaining the plug in position in the well. The lower end of pipe E is formed with an upturued ilange, e, which bears against the bottom of the plug C, and prevents the said pipe from being forced through. the plug by the pressure of the gas or fluid.

The operation of our invention is as follows: rlhe plug (l is first passed down upon thepipe C until it rests upon the flange c. The valve or cock F is now opened,and the plug is forced down into the well until the fiange c is below the strata of rock immediately above the sand. rlhe pressure of the gas 'or fluid in the well acting upon the flange @,spreads the latter out 9 below the edge of the rock or against the sides of the hole, and the plug is thereby held securely in position. The annular wedge G- may n ow be dropped down upon the top ofthe plug, assuming the position shown in the drawings,

IOO

for the purpose of further securing the plug in position; but it will generally be found that the pressure of gas or uid will press the flange c out against the rock with sufficient force to hold the plug rmly in position. being held in position as described, the flow of gas or fluid can be readily controlled by opening or closing the Valve or cock F, and the casing being relieved entirely from pressure, there is no danger of blowing out the saine.

fe are aware that it is not new to introduce a pipe into a Well, said pipe being packed below the casing and provided with a valve or cock; hence we do not claim the saine.

Vhat We claim ils- 1. A plug for gas or Artesian Wells, consisting ofa body of rubber having a central oriice for the passage of gas or fluid, and afiange upon its lower edge adapted to be pressed against the sides of the well by the pressure of the gas or fluid from beneath,whereby the plug is held in position, substantially asdescribed.

2. A plug for gas or Artesian wells, consisting of a body of elastic material having a central opening for the passage of gas or fluid, and provided with means, substantially as de rlhe plug scribed, whereby the pressure from beneath will expand the plug out against the sides of the Well, thereby retaining it in position, as set forth.

3. The combination, with plug C, provided with means, substantially as described, for securing it in position in a Well by the pressure of' the gas or fluid, of the pipe E, passing through said plug, and provided with a ange. e, to prevent the'passage `upwardly of said pipe through the plug, as set forth. 5 4. In a gas or Artesian Well, the combination, with the well, of a plug inserted therein and held in position by the pressure of the gas or fluid, a pipe connected to said plug and provided with a suitable valve or cock, and means, substantially as described, for operating said valve from the surface, as set forth'.

In testimony that we claim the foregoing asv our own We have hereto aixed our signatures in presence of two Witnesses.
